Abstract (en)

[origin: EP2249221A2] It is an object of the present invention to provide a controller for a machine tool and a five axis simultaneous control machine tool controlled thereby which can improve machining accuracy in controlling a pivoting axis of the machine tool. The controller comprises an allowable position error setting member 101 setting an allowable position error ” between a commended machining position P1 and an actual machining position P2, a velocity control parameter deciding member 103 deciding a velocity control parameter of the pivoting axes of the A-axis and the B-axis in accordance with the allowable position error ” being set and a distance of said actual machining position P2 from the pivoting axes of the A-axis and the B-axis, and a controlling member 104 controlling a velocity of the pivoting axes of the A-axis and the B-axis based on the velocity control parameter.
